UNITED STATES CHARLEY REUTER AND OSCAR SCHILLING, OF WARSAW, ILLINOIS.

REPRODCER.

Application led May 31,

To @ZZ who/m t may concern:

Be it known that we, @HARLEY Rntrrnn and Oeoan SCHILLING, citizens of the United States, residing at Varsaw, in the county of Hancock, State of Illinois, have invented a new and useful Reproducer, of which the following is aspecification.

This invention relates to phonog 1aph ren'oducers, the primary object of the invention being to provide a reproducer which will not be effected by jars or vibrations of the machine to which the reproducer is applied, to the end that the record being played will send off regular and unbroken 7 sound waves.

A further object of the invention is to provide means for insuring the proper tension of the stylus in the sound grooves of the record.

A still further object of the invention is to provide means for securing the stylus in a perpendicular position, when irregularities are encountered in the record tablet.

lith the foregoing and other objects in view which will appear as the descript-ion proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a bottom plan View of a reproducer constructed in accordance with the present invention.

Figure 2 is a vertical sectional view through the reproducer.

Figure 3 is an elevational view of the reproducer, a portion of the upper section being broken away.

Referring to t-he drawing in detail, the reproducer forming the subject matter of this invention comprises an upper section 5 and a lower section 6, the upper section being provided with a depending circumferential flange 7 adapted to embrace packing S, which contacts with the diaphragm 9 of the reproducer, to support the diaphragm in proper relation with the walls of the sections 5 and 6 to permit the same to vibrate.

The sections of the reprodncer are secured 1921. Serial No. 473,594.

together, by means of the bolts 10 which pass through the lateral enlargements 11 disposed in spaced relation ou the periphery of the sections, there being provided nuts 12 operating on the bolts 10 for drawing the sections into close engagement with each other. Secured to the lower section 6 is a depending arm 18 which has a right angled extremity 14- lying in spaced relation with the lower section of the section 6, the right angled extremity 14 being provided with a tapered opening to accommodate one end of the pivot pin 15 which has its upper extremity seated in a tapered opening in the section 6, so that the pin may move freely to accomplish the automatic adjustment of the stylus support to be hereinafter more fully described.

Secured to the pivot pin 15 at a point intermediate its ends, is a bearing member 16 which has spaced arms 17 through which extend the pivot pin 18 that connects the stylus support 19 to the bearing member 16. Encircling the. pivot pin 18 is a coiled spring 20 which has one end contacting with the bearing member 1G, the opposite end thereof being passed through a suitable opening in the lug 21, secured to the bearing member 1G, the action of the spring 2O being to normally urge the stylus support 19 away from the body portion of the reproducer.

The outer extremity or free end of the stylus support is forked to provide the arms 22 which lie under the angularly disposed arms 23 of the keeper 24, which depends from the lower section 6 of the rcproducer, the same being secured to the reproducer at a point directly opposite to the point of connection between the arm 13 and the lower section 6.

From the foregoing it will be seen that due tothe angle at which the arms 23 are disposed, the stylus support is moved to the center of the reproducer after the same has been moved laterally, due to the contact of the stylus carried by thc stylus member, with an irregularity on the record tablet.

Depending ears 25 form a part of thc stylus support 19, through which ears extends the pin 26 that connects the stylus arm 27 to the stylus support, one end of the stylus arm being provided with an opening to accommodate one end of the rod 28, the opposite end of the rod being positioned in the. securing means 2f) that has connection with the diaphragn'i 9 at a point centrally thereof.

Positioned within the socket member' formed in the free end ot the stylus supporting arm 27 is the usual stylus SO which moves in the sound grooves of the record tablet, to transmit certain movement to the diaphragm 9.

In the use ot the reproducer constructed in accordance withv the present inventimi7 it will be seen that the body portion ot the reproducer moves in a true plane at all times, all irregularities or vibrations which are ordinarily directed to the body portion oit the reproducer, being compensated 'for by the movement ot the stylus support 19, and the stylus supportingv arm 2T.

lWhat is claimed as nenv is:-

n a reproducer, a body portion including separable sections, a diaphragm positioned between the sections. an arm secured to the body portion and having a right angled end arranged in spaced relation therewith to provide a bearing7 a vertical pin arranged between the body portion and bearing, a bearing member mounted intermediate the ends of the pin, a stylus support pivotally connected to the last mentioned bearing member and adapted to move in a vertical plane, a spring member having connection with the stylus support to normally hold the stylus support downufardly, said stylus support having a central opening7 a rod having connection with the diaphragm and extending through the central opening, a stylus arm pivotallv mounted on the stylus support, said rod having connection v-Cith the stylus arm, and a support tor the outer end ot the stylus support to permit the stylus support to move vertically and laterally.

In testimony that we claim the 'foregoing as our own. we have hereto al'lixed our signatures in the presence` oit two witnesses.
